Vivian Campbell figured he was in the clear last fall when tests revealed that the Def Leppard guitarist was cancer free after a regimen of treatments to fight Hodgkin's Lymphoma, but Campbell recently told listeners of Gater 98.7 in Palm Beach Florida the disease '...seems to be, kind of, coming back again.' That said, Campbell turned upbeat, saying, '...it's just a process to get though. I mean, like I said, It's absolutely nothing I'm concerned about, but it's something I need to start the process, I need to get a handle on, so that I'm free and clear to tour this summer.' His group and KISS are cued-up for a summer co-headline tour.
